Hello, Folks. I still keep trying to do accomplish my goal: To play scores at my own pace. In order to do that, I finally designed a 'rhythm remover' software for the MIDI scores, making all notes 'quarter notes'. I then played the score with the step function on MuseScore (> on the computer keyboard). It works fine, except for the fact that I cannot keep the note playing for long notes played by me, at will: MuseScore always plays now a short note, a 'pulse' generated by its software. Bottom line: Does anyone know an EASY way to keep the note playing until I release the > key on my QWERTY computer keyboard? Thanks much! Cheers, Julian



  1. You'll need to assign sounds that don't naturally decay (so no Piano/Guitar for example)
  2. Open the Play Panel and turn the tempo slider all the way down so it plays really slowly; consider adding slower tempo markings to the score for even more slowdown (or a plugin such as TempoStretch)
  3. Start Playback
  4. Use right-arrow to make it advance faster than it is.

The tempo slider in the play panel is a temporary override thing that doesn't get saved between sessions. But you don't have to reset it on every play; only when you reload MuseScore.

Tempo markings in a score are saved within the score

The other things aren't settings.

Hello again, jeetee

That works well for standard playback, but not for "EXTEND NOTE TIME WHEN PLAYING WITH > STEP FUNCTION", my need, unless I made a mistake. Do you think there is any other way to make it happen?

One more question, please: Can I use the > step function with MuseScore on my Android and Apple cellulars?

Thank you again. Julian

PS: For question 1, I think there was a misunderstanding. You are right, only that I have to go to the PLAYBACK function first and from there use the > key. Now, since you were the creator of TempoStretch: I downloaded and installed it, but I don't find it on the score with a slider. With F11, I opened a tempo slider, but the minimum tempo I get is 10 BPM. Is that value reached with the installed TempoStretch? I would need something around 5 BPM or even less if possible at all...

Thank you!

The scrubbing method is during playback indeed. As for whether the mobile apps support such a function, you'd have to ask over at the .com site. The mobile apps are not part of the open source notation software effort.

The temposlider in the play panel is the built-in temporary tempo override; changing this slider affects playback but does not change your score.
If you've enabled the TempoStretch plugin you also need to run it. The plugin also shows you a slider/value where you can change the tempo of the score from 1% to 400%. The plugin changes the score. It updates all tempo markings in the score to achieve the desired playback tempo. The plugin applies either over the selected range or the full score (if nothing is selected).

Rather than throwing a video inside a word document, consider sharing your actual score itself; so we can inspect the tempo marking inside it. Your video doesn't show the tempo properties, nor the plugin running/being run, nor the playback toolbar; so it is lacking way to much information to be of any value.

Just attach the mscz itself and tell use where to click/what to do to see what is going wrong for you and what you'd expect instead.

Thank you for your prompt reply. Now, the reason I am sending you the video is because it is the only way to practically show what I need. This result (playing note by note with a violin with MuseScore) was achieved via a different music forum, but whoever did it never explained how…

If you go back to my posts (Jan 30, 2022 - 20:45, Mar 6, 2022 - 17:18) it will probably refresh your memory regarding my needs. However, let me rephrase them in simple words:
1- I open the only quarter notes score in MSC4 (attached).
2- I choose an instrument to play it.
3- I click on top of the clef.
4- I start playing with the > computer key.
So far so good, but for sounds that don't naturally decay. If I want to play a violin, for example (as shown in my video), the notes must be stretched.

Our project runs on a sophisticated microprocessor instrument built with the aid of the Colombian Government Laboratories (see attached picture, please) to be used with MuseScore, and with the purpose of playing music, especially for children and disabled persons (also adults). With this microprocessor device we can silence gradually or totally the stretched notes at will at any point of the MuseScore file. That way, we can control all the score sounds’ volume. I think your TempoStretcher would be extremely useful for the project.

In summary, I need simple step-by step instructions (1,2,3…) in how to achieve this goal.
Would you help, please?

Thank you!

Hello, again.
While I wait for an answer from jeetee or some other folk who could be kindly ready to help, I prepared another score: nothing but quarter notes; needing 10 second duration max for all notes and using the step function “>” on the computer keyboard to play note by note (my own rhythm) with TempoStretch or in any other way. See attached, please.
Can it be made? Sounds simple for an expert to solve… (not a layperson like me) If not: May it be possible that MusiScore4 is defective (glitch) and cannot perform in the step mode? If so, who would be able to fix it?
Thank you!

TempoStretch does not change the live playback of a score, it changes the tempo markings inside it. A step you're currently missing (or didn't clarify) is to actually start very slow playback by musescore itself. The arrow key is then only used to "speed through" the very slow playback it is performing.

1- I open the only quarter notes score in MSC4 (your MAR TEST.mscz).
2- I choose an instrument to play it. (I chose the Violin 1 (solo) instrument from Muse Sounds)
3- I ran the TempoStretch plugin and set it to 1%. You'll see the tempo indication (1/4 = 100) change to (1/4 = 1).
4- Click on the very first note in the score.
5- Press spacebar to start playback.
6- Advance to the next note when desired by pressing the right arrow key
